On Computation and Communication with Small Bias
We present two results for computational models that allow error probabilities close to 1/2. First, most computational complexity classes have an analogous class in communication ...

Low-Complexity Distributed Scheduling Algorithms for Wireless Networks
— We consider the problem of distributed scheduling in wireless networks. We present two different algorithms whose performance is arbitrarily close to that of maximal schedules,...
